Hubei roller crusher manufacturers have a good reputation and are more professional

 

    In the past ten years, the application of hydraulic technology in the roller crusher has been further developed. At present, the main focus is on the application of hydraulic principles to adjust the discharge port and insurance. This overcomes the disadvantages of difficulty in adjusting the discharge port of conventional crushers and poor reliability of safety devices.

 

    At present, the spring-hydraulic medium-fine crushing cone crusher used in some production plants in our country is a partially improved product on the basis of the roller crusher. The structure mainly adds a hydraulic locking cylinder and a hydraulic pushing cylinder. The former is used to fix the support ring and the adjustment ring (that is, to lock the fixed cone); the latter is used to adjust the discharge port. Its safety device still uses the spring safety device. The one that can be used as the development direction of hydraulic counter-roll crusher is the bottom single-cylinder hydraulic counter-roll crusher. The increase or decrease of the oil volume in the oil cylinder causes the movable cone to rise or fall to achieve the purpose of adjusting the discharge port.

 

    The overload safety function of the machine is achieved by a piston accumulator connected with the high pressure oil circuit under the piston of the hydraulic cylinder. It is filled with nitrogen (50-60 kg/cm2) whose pressure is higher than the oil pressure required for normal crushing. When iron or other non-broken objects pass through the crushing chamber, the oil pressure in the high-pressure oil circuit is greater than the pressure of nitrogen in the accumulator, and the oil enters the rose energy device, the crushing cone drops, and the discharge opening increases. Excluded, the machine reaches insurance. The bottom single-cylinder hydraulic roller crusher is simple in structure, easy to manufacture, easy to operate, and easy to automatically control. It is a hydraulic crushing equipment with better performance. It can be used for medium and fine crushing of hard ores. The use of hydraulic technology not only overcomes the shortcomings of difficulty in adjusting the discharge port of the crusher, but also improves the production capacity of the crusher equipment, and has excellent performance for crushing medium-hard and hard ores.

 

    ??With the continuous development of mining technology, there are several types of roller crushers, including spring roller crushers, mortar cone crushers, hydraulic roller crushers and composite cone crushers.

 

    Crushers are divided into four categories; according to the model, they are divided into ordinary PY roller crushers, Simmons roller crushers, composite roller crushers, standard hydraulic roller crushers, single-cylinder hydraulic roller crushers and multi-cylinder hydraulic roller crushers Roll crusher and many other models. The hydraulic crusher is developed on the basis of digesting and absorbing various types of roller crushers with the international advanced level in the 1980s. It is obviously different in design from the traditional roller crusher, and it concentrates the main advantages of various types of roller crushers known so far [2]. It is suitable for fine crushing and superfine crushing of hard rocks, ore, slag, refractories, etc.
